How I can maximize this problem using the KKT method?
f(u,z,l)=(xz)2+l2
with the next conditions:
3x+2z+l=24
x≥0;z≥0;l>o
x+z>0
I do the next lagrangian:
L=−(xz)2−l2+a(3x+2z+l−24)+b(−x−z)
and then I have the KKT conditions:
−2xz2+3a−b≥0 (−2xz2+3a−b)x=0
−2x2z+2a−b≥0 (−2x2z+2a−b)z=0
−2l+a≤0 (−2l+a)l=0
3x+2z+l−24=0 (3x+2z+l−24)a=0
−x−z≤0 (−x−z)b=0
But then I don't know how to get the solutions.
Thanks
